Title: Neuromorphic Meets Neuroprosthesis
Neuroprosthesis is a perfect example of brain machine interface with a clinical purpose and human benefit to amputees. Neuroprosthesis uses interface to the nervous system to derive signals that code for prosthesis movement. Reciprocally, neuroprosthesis would receive sensory information from the prosthesis and deliver it to the nervous system for sensor perception and cognition. Therefore, the ultimate dream today is bidirectional neuroprosthesis with sensory-motor control. I will focus on sensory neurorprosthesis and address the question: how to deliver the desired sensory information to the nervous system. Here, we take the approach of sensing from tactile, visual and other sensory systems to give feedback to the nervous system. Neuromorphic encoding takes the receptor inputs to convert into the neural signal, essentially a stochastic spiking pattern. I will present how tactile and visual signals are encoded and used for closed loop neuroprosthesis. Armed with neuromorphic encoded tactile input dexterous multi-finger prosthetic hand gains the capability to touch, palpate, grasp and manipulate. Neuromorphic approach may provide a more natural biomimetic approach to closed loop prosthesis. Future directions include multisensory integration and developing implantable interfaces to the nervous system for neuromorphic neuroprosthesis.
